HB_IO
Harwell Boeing Sparse Matrix Files
Read and Write Utilities


HB_IO is a C library which reads and writes files in the Harwell Boeing sparse matrix format.

A special feature of HB_IO is the routine HB_FILE_READ, which can read all the information from an HB file of arbitrary size.

Note that the most common "flavor" of HB file is an assembled sparse matrix, but that there are some lesser used options, including storage of the matrix as unassembled finite element matrices, and corresponding storage of vectors. These secondary options are less well documented, and are only marginally supported in this package.
